I'm wanting to see if it would be possible to open the existing iRealb/Pro forum library of tune files in another program, that I would develop... I could only find reference to the "legacy" .irb format, which apparently is not how charts are currently saved. Can they be opened in a code or text editor? There had been some mention of data obfuscation entering in with the advent of "Pro" (as opposed to "b"), but wasn't quite sure what was meant by that, exactly. Sorry if this is a question that gas already been addressed or should be handled with Massimo directly.
